Description:
you need to determine the floating voltage of the rechargeable battery and the charging current, input voltage module adjust the constant voltage potentiometer, and adjust the output voltage to about 5V. use multimeter 10A current block to measure and output short circuit current, adjust constant current potentiometer at the same time, make output current reach the predetermined charging current value charging, turn the light current default to 0.1 times the charging current (constant current value), if you need to adjust, please adjust the current switch potentiometer; (generally do not adjust) to adjust the output voltage of the constant voltage potentiometer to float voltage connect the battery, test charge. LED constant current driving method: make sure you drive the operating current and maximum operating voltage of the LED adjust the constant voltage potentiometer to make the output voltage reach the highest working voltage of the LED connect LED, test machine.
